$Epipactis helleborine, the broad-leaved helleborine, is a terrestrial species of orchid with a broad distribution. It is a long lived herb which varies morphologically with ability to self-pollinate. \nDescription:\nEpipactis helleborine can grow to a maximum height of 1 m or more under good conditions, and has broad dull green leaves which are strongly ribbed and flat The flowers are arranged in long drooping racemes with dull green sepals and shorter upper petals. The lower labellum is pale red and is much shorter than the upper petals. \nFlowering occurs June–September. \nHabitat:\nFound in woods and hedge-banks and often not far from paths near human activity. It is one of the most likely European orchids to be found within a city, with many sites for example in Glasgow, London and Moscow. Sometimes spotted beside car parks. \nEpipactis helleborine is known for its successful colonization of human-made or anthropogenic habitats such as parks, gardens or roadsides. These roadside orchids exhibit special features such as large plant size and greater ability to produce flowers. Pollination plays a huge role as pollinators such as Syrphidae, Culicidae, Apidae etc. possess greater species diversity and visits the flowering sites more in anthropogenic habitats as compared to native ones. The visitation rates along with the reproductive success of these orchids are higher in large populations as they are more attractive to pollinators. \n\nDistribution:\nThis species is widespread across much of Europe and Asia, from Portugal to China, as well as northern Africa (source Wikipedia).\n\nThis is a very common Species in the described Habitats in the Netherlands.$
